50 pound salt block.
This 50 pound block of salt cost $4.99. That's right, 10 cents a pound retail for something once so valuable that the very word salary derives from it. In solid block form salt like this is meant for licking by cattle. It's called a salt lick and you get them at farm supply stores.Source:Farm & FleetContributor:Theodore GrayAcquired:28 February, 2009Text Updated:1 March, 2009Price: $5Size: 12"Composition:NaCl
